Abstract
A unitary diamond bit/holder, tool, and/or pick assembly that includes a forward extension axially extending from a body of the bit/holder and a tungsten carbide ring mounted in an annular trough at a forward end of the body around the forward extension. An axially shortened diamond tipped bit tip insert is brazed to the forward extension, within a bore of the forward extension, and/or to a tungsten carbide plug which is then seated within a bore of the forward extension.
